SHINGLE FABTENING.

Application med November a, 192:1. seria; 1m $3,524.

This', invention i'elatesjgenerally im roof coverings of the shingle type but is particularly applicable to liexible shingles, which are usually made by impregnati'ng a some weet flexible fabric, suvli as asbestos felt, Willi asplialtmn or other hydro-carbon nml with or wtlieut u surface Coating of grannlzii mineral material. More especially the in `xent'ion is designed to be embodied inve elim-- gle roof of this type in which snletantully square shingles are luid in courses 'with their diagonal dimensions in horizontal undY verl i ml plaines, thereby producing :i pointed shingle ell'ect.

In roof coverings of the last allow mvo.- tioned type it impormnt to ,eef-umili' fame en the downwardly exlending poim or ex tlmity of each hing/le to prvient the eine being curled upward liy the Winsil oi in". nu# eqlml commotion l expsmzfion in the lioiiy of the shingle, i so as mail mali lower' portion of one slim extends out beyond the edges of the ehi of the nexily lower course, lo ,suppiy s: im onnlfil'ion over which said filonid 'dawned without bending or hse??? Wn over ille edges of said sllnglef:y i n; lower Gouwe.

This invention, these desirable re sulte by placing; such lower portion of each shingle :i re l triangular porien of the Shingle infr! ,i wing o rldgi (whiffln of course, is of ll f can; l fri'nffss :is the :miv jacent shingles of the a lower comme lueVm tween which it will rzril fmn nvm/n ing a ilnrbshapeil o'ielfm mon 'for eaiil flap which will have lumi-w, minimi exzensions on its lie-ml, .which em slipped imfiei' the 'fuljucenb si" next lower course when a serine m gies have been nailed to a roof fi-4f? usual way.

The best form of anpmat-us et g'fresen known to me embodying this invention is ilI leiatrnml in the iieompenying sheet. of flrznvf ings in which:

Also as is not always 'essential to fasten 5 the plate 3 on the particular side of flap 2 on which I have shown it in the drawings.

Obviously also, modifications might be made in the arrangement of the shingles of the various courses to produce a greater E0 or less amount of overlap or a different visual effect inthe completed roof so long as the principles of the invention above dcscribed are retained.

The atlvanta es of the invention comprise` if among other tiing's, its simplicity. ense ol,

application, security of fastening und econ only of'material. The triangular flap por-- tion 2 forms a. foundation having its upper surfaces inthe plane of the upper surfaces i' ot' the shingles of, the next lower course so and break ythe shingl` that the shingle to which it is attached will not bend downwards under any vertical pressure applied to attr: is in position. (Vonscquently there ,is no tendency to flex "at any pointnfter it 'is in position for use. Also the triangular' Hap portion 2 fits closely into and tills the triangular space existing below the lower portion of each shingle and lieiweci'i the :idjaccnt edges of the shingles of the next. lower course l, and so prevents rain from being driven up into this cavity, or the collection therein of foreign matter which might tend to softegi or ret the shingles above and beneath and on either side of, such cavity.

,sus

The dart shape, or wedge outline, of plate 3 is important because it facilitates the insertionof the plate under the edges of the shingles of the next lower course, the pointed tip 3 readily penetrating and easily dividing lany mass of obstructive matter which may have been left under said shingles. This is especiallyY helpful in patching an old roof by insertion of new shingles at separate points.

Having described my invention,'I claim:

A roof covering composed 'ef pointed shingies comprising, in combination, a plurality of courses of substantially square shingles, cach course arranged with one set of the diagonal dimension of its constituent shingles horizontal und with the corners of adjacent shingles touching, each such course slightly overlappinpr the 'next lower course, the lower corner of each shingle being bent under from exposed position and forming a fla p placed under it in the vertex of the angle between two adjacent shingles of the next lower course, yand a thin quadrangular plate ofl stiff material, having one corner clipped olf to an extent such that the cnt edge approximates in length the line on which said flap is bent, fastened to said folded flap and extending beyond the point anddioth sides of said flap and under said adjacent shingles of the next lower course; whereby said flap, and the lower portion of the shingle to which it is connected, are firmly anchored in position.
